New Zealand researchers compared the health risks posed by steamers and cigarettes, respectively, by analyzing the current scientific literature. They concluded that the first products were much healthier and could save millions of lives.
Scientists at Auckland University have evaluated the hazards of cigarette smoking and vaporization using the analytical model proposed by the Environmental Protection Agency (EPA). Of the twelve compounds studied in the scientific literature as being of greatest concern, they identified two substances in the electronic cigarette that have average exposure levels slightly above international safety standards, acrolein and propylene glycol. A conventional cigarette produces five substances at average exposure levels above international safety standards: acetaldehyde, acrolein, formaldehyde, cadmium and nitrosonornicotin. These researchers presented several findings in the International Journal of Environmental Research and Public Health. According to them, steamers could be much less harmful substitutes than cigarettes for people seeking to quit smoking. "Our research provides evidence that supports the analysis of the British Department of Health (PHE) but follows a different methodology." Said authors of the study. However, they explain that these results must be interpreted with caution. They encourage consumers to avoid products of inferior quality, which may expose them to higher risks than very good quality vape kit. For example, they call for the introduction of manufacturing and quality standards to prevent the sale of poor quality devices. In addition, they felt that further research is needed to assess the hazards of exposure to sprayers. Obviously, the scientific literature on conventional cigarettes is much richer than that on electronic cigarettes. Finally, these scientists at Auckland University did not declare any conflict of interest.
